Rinnai tankless water heater vertical vent installation

The supplier sent me a horizontal vent package and I need the vertical package. Mechanically, I can see that it is easy to install, but identifying parts of the vent system is confusing as to exactly what I need to order.

What is the minimum vertical vent distant from top of water heater to top of cap. Water heater is stand alone outside furnishing water for military force provider showers unit.


Generally 40 feet for ordinary atmospheric-vented household water heater...
Straight run to roof.
Atmospheric means no power vent... just hot air drafting upwards
Google search: gas vent height code

Atmospheric venting code depends on 4 basic factors:
Diameter of vent--- bigger vent, more draft
How many water heaters are connected to same vent
BTU per hour rating of water heater-- the more gas that is burned per hour, the bigger the vent needs to be
How straight the pipe is -- are there any horizontal or lateral runs

http://waterheatertimer.org/pdf/Bosch_Checking_the_draft.pdf
http://waterheatertimer.org/pdf/checking-the-draft2.pdf

Other factors can include
-wind conditions... higher wind across top of vent pipe on roof can reduce draft, and cause downdraft that blows deadly CO into same room as water heater
-vent termination near high walls, trees, high roof peak etc will reduce draft or cause downdraft
-amount of incoming air supply... if water heater is inside a closed room, then there is no air to draft up the pipe, burner will shut down or burn lazy yellow instead of clear blue
-stuff piled up around water heater that obstructs air intake
-dirty air intake screen that reduces air intake
-vent fans inside same room as water heater that pull air down the vent and cause reduction in water heater draft
-generally elbows reduce draft by 10%
-vent cannot terminate near any window door or air intake for another gas appliance
-bird build nest on top of vent pipe after vent termination falls off
-highly acidic gas by-product causes large amount of condensation inside pipe that burns hole in pipe or drips down and damages combustion parts...blower and inline condensate trap and drain might be required
-multiple water heaters installed on same vent line.

Have 75 gallon gas water heater. Can I run 90 PVC off top power vent without vertical PVC first? Have Richmond unit.


1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#venting

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.

More information is needed.
Water heater is not identified.
Add a comment with more information from label on side of tank.

If you have gas water heater, then open following links to identify gas valve, and download error code diagnostic and possible service manual:

http://waterheatertimer.org/How-to-install-gas-water-heater.html#troubleshoot

For power vent water heater with Honeywell gas valve: three flashes indicate pressure switch or blower temperature switch not working.
Typical causes appear on page 13 on manual: can be bad blower, bad switch, blocked vent, exhaust temperature too high.

I have a 50 gallon rheem direct vent natural gas heater. The pilot light goes out on an infrequent but aggravating basis. I replaced the thermocouple one time and it got better for about a year but has...


Open following links for pilot light help:
http://waterheatertimer.org/How-to-install-gas-water-heater.html#troubleshoot
http://waterheatertimer.org/pdf/Pilot-light-will-not-stay-lit.pdf
http://waterheatertimer.org/images/Negative-pressure.jpg
http://waterheatertimer.org/pdf/Bosch_Ventilating_tight_houses.pdf

Since pilot light goes out and can be re-lit, problem is probably not thermocouple, gas control valve, or air in gas line. But these things can factor in as contributing factors.
Problem is likely one of following or combination of following including dirty burner parts, tight house, incorrect vent lengths, negative pressure caused by other venting appliances, condensation dripping down into combustion area, and inadequate oxygen supply due to hot or closed-off room or attic location.

Gas water heaters draw air from surrounding area. If water heater is located inside house, then air has to enter home through cracks and when doors and windows are opened. Other gas appliances and vent fans also draw air from same indoor area. When other vent fans turn on, air can be drawn down the water heater vent and blow out pilot light.
Inspect combustion chamber to make sure there is no condensate water dripping down from incorrect vent that is putting out flame. If combustion chamber is dry, then close doors and windows. Turn on all vent fans and gas appliances that vent outdoors, and see if water heater pilot goes out.
Consult with plumber or product manual about proper horizontal and vertical lengths of vent pipe for your model. Have plumber clean combustion parts and inspect vent termination and check gas pressure and bleed gas line.
Add louver opening to outdoors so air can enter room where water heater is located.

My paloma tankless gas has a error code c2 11 c4 12 why


Open following link for useful troubleshooting information:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 11 is 'No ignition'
http://waterheatertimer.org/pdf/Paloma-Tankless-Error-Codes.pdf

Ensure you have gas to the appliance.
Ensure gas type and pressure are correct.
Bleed all air from gas lines.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Ensure igniter is operational.
Check igniter wiring harness for damage.

Error code 12 is 'Flame Failure'
Ensure you have gas to the appliance.
Ensure gas type and pressure are correct.
Bleed all air from gas lines.
Ensure flame rod wire is connected.
Check flame rod for carbon build-up.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Check power supply for loose connections.
Check power supply for proper voltage and voltage drops.
Disconnect remote control.
Disconnect and re-connect all wiring harnesses on unit and PC board.
Ensure proper venting material was installed.
Ensure condensation collar was installed properly.
Ensure maximum vertical vent length does not exceed allowable limits.
Ensure maximimum horizontal vent length does not exceed allowable limits.

Range of causes are part failure, gas pressure loss, air in gas line, improper installation of gas line or vent, 120V power to unit is disrupted or unit not grounded, circuit problems, venting problems, remote control, wiring to PC board, board failure, carbon build-up on flame rod, short circuits on gas valve solenoids.
The fact that you have error code tends to eliminate your plumbing as culprit, the error code does not mention air supply, otherwise it looks like every possible cause is on the table.

It seems that you have this figured. In their literature all units are shown vertical, either inlet up or inlet down. Also, it appears that if the unit is full of water, (water logged) pressure will build up in the system. Temporarily, you could shut off water to the water heater, open some drains and use a pump to put some air back into the tank. This would at least get air into the upper half of the tank for a while until you can get set to make a repair.

I have a whole house water filter that uses a 30 micron FXHSC filter. the last two filters have come apart and sent fiber through the water lines in the house


Hi,
I would shop around for a different water filter supplier...there is no reason ofr that happening unless you are not changing the filters regularly...like once a month...
most filters are a standard size and it should be easy to get them somewhere else...

I would say that the wood fire/stove must have a heck of a draw to affect the bathroom heater. Maybe a separate air supply from outside via a pipe,to the stove meshed off against vermin would decrease the problem. Plus it could stop cold air being sucked across the room from an outside door.
Downdraft through the heater could happen with either vertical or horizontal vent. More important is the direction of the prevailing wind [horizontal] ingress of water/snow etc [vertical]
We often use the separate air supply in the UK and if the pipe bore is large enough 4" plus it seems to work ok.
